This hypertufa trough, planted only weeks ago, is doing remarkably well. I used a technique I read about in the North American Rock Garden Society quarterly, and sandwiched a thick clay mud between vertical slabs. One would think that the little Erigeron pinnatisectus or Feather-leaf Fleabane, perched at the top, would not have had a hope of surviving, but this is a plant of steep slopes and high ledges, and it seems to be thriving. Let’s see how this little garden survives the winter.
